You can buy a complete key blade and fob but the key needs to be cut and the chip needs to be programmed to the car for it to start using JLR/SDD. The fob can be programmed manually to perform it's functions quite easily though without JLR/SDD.
The key and fob are two separate parts. The fob buttons (lower portion )can be programmed yourself. The chip (upper part containing the key) has a chip that has to be programmed to the car before it will start the engine.Getting totally confused now? So if i buy a new fob with key that needs to be cut, i can programme the fob, but i will also need to take it to a main dealer to get it programmed by them as well?
The fob part which locks/unlocks the car can be programmed by you, but for it to start the car with the blade, it will need programming using IDS/SDD software.Getting totally confused now?

That's a new one on me. The key transponder does not use a battery. It is read by the receiver around the ignition to cancel the immobilizer. I believe the code is a rolling code so perhaps the 15 second may be something to do with that. Turning the key in the door lock will turn the alarm off.Timpson should be able to make you a Tibbe cloned key that will start the car , no remote functions though.
When you open the car with the key you will need to get it in the ignition and turned on within 15 seconds to stop the alarm going off.
The cloned key has a battery in it and produces exactly the same transponder hand shake as your original key , around £45
As above post , if you lose your only key it will cost you a lot more from a dealer / other to rectify.
